The Octagon(1980) [Kyo/Long Legs]: Playing a dual role, "Long Legs" is shot in the chest in a shoot-out with Lee Van Cleef's men. "Kyo" is burned to death after being knocked into a fire at the end of a fight with Chuck Norris. (Richard's face was hidden by a mask for his role as "Kyo.") (In the behind-the-scenes feature on the US DVD, Richard also states that he played several of the masked ninja in various fight scenes and "died eight times.")

(Note: As a professional stunt performer, Richard has probably "died" in place of other actors, though I don't know any specific examples.)
